Name of isindex or form field

$Web_Name retrieves the name of an isindex or form field in a request.

$Web_Name takes a single argument and returns a string or null if the number references a non-existing field.

Syntax

%rc = $Web_Name( field_number )

Syntax terms

The only parameter is the number of the isindex or form field for which the name is being requested. This parameter must be specified.

Usage notes

  • $Web_Name is useful when writing generic server applications, when the server does not know what field name exists at a particular location in an isindex or form request. For example:

    * Get the number of isindex or form fields. %x = $Web_Num * Load the field names into an array. For %y From 1 To %x %field(%y) = $Web_Name(%y) End For

  • $Web_Name first counts isindex fields and then form fields. $Web_Name can be used instead of $Web_IsIndex_Name and $Web_Form_Name to make it easy to switch between using "method=GET" and "method=POST" <form> tags and simply to save typing.
